You might have to check for loose connectivity or dry solder connecctions in the power supply or the mainboard of the set.
This can be possible only by a good inspection of the board. Tap on to see if the set powers back, if so there are dry joints in the board.
If not check for components that are heating up, it can be loosing connection with the leads having poor contact .
Solder all IC pin leads and connections of power drives.

I have repaired this kind of problem in a Samsung smart LED TV. It appears to be backlight problem and you need an expert TV Tech to repair it.
By the way, it will be of great help to us while suggesting the solutions if you please mention the model number and Brand of your TV.
Thanks

Power will turn on for a brief moment then turn off again. Won't stay on longer than a split second.


Sounds like you have a problem with your TV power supply if you still have it under an extended warranty it is best to get it service.

TV turns on for 2 second and then it is off


Your TV may have detected an error. Try first to have the TV unplugged overnight just to clear it out then observe it after turning it back on.

New TV 9 mos old, Won't stay on after power up? Remote or manual turn on, set keeps turning off after 1-2 second green on and brief screen flash.


I would try leaving the TV unplugged for 30mins so the TV can reset itself.
If that doesn't work, your TV should still be under warranty. I know 95% of come with a 1 year warranty.
The most common problem with Sylvania TVs made by FUNAI, the Backlight Inverter board fails to early in life. ( That's the part that powers the screen)
The Tv can't power up the screen and it turns off automatically. Basically called "Protection Mode" so it protects the other parts inside the TV.
